Meaning and usage
Often denotes a manifold, model class, or mathematical structure.
Use it with a definition, especially when several styled M symbols appear in one document.
Pronunciation: script capital m
Formula examples
x\in\mathcal{M}How to type Script Capital M
- Windows
- Use Character Map and search for Script Capital M, or paste the Unicode character (U+2133).
- macOS
- Open Character Viewer with Control–Command–Space and search for Script Capital M.
- Microsoft Word
- In an equation, type \mathcal{M} and press Space when Word supports the command; otherwise insert the Unicode character.
- iPhone and iPad
- Copy and paste ℳ, or use a math/LaTeX app. The standard iOS keyboard may not expose every mathematical symbol.
- Android
- Copy and paste ℳ, or use a math keyboard or LaTeX editor. Keyboard layouts vary by device and app.
- Google Docs
- For plain text, paste ℳ or use Insert → Special characters. For structured math, use the equation editor and verify \mathcal{M}.
- Excel
- Paste ℳ into a cell or use Insert → Symbol when available. Ordinary cells preserve the character but do not interpret LaTeX commands.
Common mistakes
- Do not substitute a visually similar Latin or differently styled character for ℳ; case and mathematical alphabet style can identify different quantities.
- For plain text, copy ℳ as U+2133; for structured equations, use \mathcal{M} in math mode. A look-alike glyph or image can break search, accessibility, or parsing when the intended character is Script Capital M.
When to use ℳ
- Use ℳ in plain text when a Unicode character is appropriate and the destination preserves U+2133.
- Use \mathcal{M} in an equation editor when mathematical spacing or structure matters.
- Define the local meaning when Script Capital M is used in math alphanumeric, geometry with a field-specific convention.
Look-alikes and related characters
- ℒ — Script L
- ℝ — Real Numbers
Font and compatibility notes
Glyph shape can vary by font. Verify the code point after copying, and prefer LaTeX or MathML for structured equations.
